IGNITION SYSTEM.

Application flied May 8, 1915.

To all whom it may concern Be it known that I, LEO A. SNYDER, a-

and useful Improvement in Ignition Systems, of which the following is a specification.

tion systems, and the invention has for its object to provide a 'mechanism of the character specified, adapted for use in gas, gasolene, kerosene or other liquid fuel heating or lighting apparatus, wherein a sparking In the draw1ngs:Fi gure' 1 is a transverse vertical section of a heater providedwith the improvement, Fig. 2 is a partial front View of Fig, 1 with parts 1n secti0n, and Fig. 3 is an efilarged ve'rtical section of the switch. I

The present embodimentof the invention is shown in connection with a heater of usual or desired form, the said heater comprising a casing 1, in which is arranged burners 2, 3 and 3, the casing beingdivided into compartments as shown, the said compartments being three in number and designated at A, B and C. The burner 2 is arranged in the compartment A which is the lowest compartment, while the burners 3 and 3 are arranged in the compartment C.

A spark plug t is arranged adjacent to the humor 2, and spark plugs 5 are arranged adjacent to the burners 8 and 3 The spark plug 1 is supported in horizontal position by a bracket 6, while the plugs 5 are supported in vertical position by brackets 7 the brackets 6 and 7 being connected to the burner.

A box or casing 8 is arranged outside of the casing 1 near the top thereof, and the said box or casing is designed. to support a series of batteries 9, for generating an electric current. Acoil 10 of the vibrator type, a high tension jump spark coil ofthe class commonly used in gas engine ignition work, is arranged above the battery-box or casing, the said coil being supported at its ends by brackets 11, connected with the casing 1 of the heater, and a combination selective dis- Specification of Letters Patent.

tributer and timer 12 is connected to the outer face of the wall of the heater casing adjacent to the coil and above the same.

Leads 13 and 14: lead from the spark plugs 4 and 5, respectively, to the switch 12, the said leads being connected to suitable binding posts 15 and 16 on the switch. A lead" Wire 17 connects the arm 18 0f the switch with one of the terminals 19 of the coil and another lead 17 connects the other terminal 19 of the *coil, with one of the terminals of the. battery 9. A lead wire 20 connects the other terminal of the battery with the bindmg post 31 in a switch casing 12, which is secured to the casing 1 at any desired point, and the binding post extends through the front wall of the casing, being insulated therefrom as shown in Fig. 8. The leads 13 and 14 extend into the casing, and are connected with the buttons or binding posts 15 and 16 inside the casing, and the said posts or buttons areinsulated from the casing in the same manner as the post 21, by means of sleeves of insulating material. The wire 17-which connects one of the'terminals of the coil with the switch arm is also connected to .'a binding post 23 inside the casing, the said post extending through the front wall of the casing to a connection with the switch arm, and the post is infsulated from the casing by an insulatlng sleeve in the same manner as the posts 15-16 and 21. I

A contact member or strip 24 is connected to the binding post 21 inside the casing, and a resilient contact member or strip 25 is connected with the binding post in the casing. The free ends of the contact members 24 and 25 are arranged to be contacted when the free end of the strip 25 is pressed rearwardly by means of a push button 26, ar-

ranged within an opening in the front wall of the casing. Normally the resiliency of the member 25 holds the members 24; and out of contact with each other. A lead wire 22 connects the coil to ground, the ground connection in the present instance being through the metallic casing 1 of the heater.

The leads 13 and 14. are high tension leads for conveying the current to the spark plugs and by means of the switch arm 18, and the push button 26 any of the three plugs may be connected with the coil and battery, When the switch arm is in the position of circuit. 1 5

it is obvious that the Fig. l the device is inoperative. If for instance it is desired to ignite the heater 2 the switch arm 18 is shifted on to the button 16. The current now passes from battery through the switch coil to' the lead wire 17, and by way of the contact members 2t-25 and the lead 20 to-batter and a sparkis generated by the spark plug 4 at the burner 2.

When it is desired to connect the spark .plug 5 of the burner 3 w ith the oil,'the

switch arm is shifted to connect the button 15 at the left of the switch casing 12 to the When the arm is on the button and the button 26 is depressed the spark plug 5 generates the spark at the burner 3.. Toconnect the burner 3? withthe current it is to place the switch arm 18 only necessary F d 1g. 2, an

on the button 15 at the right of then depress the button 261 It will be evident that with the improved system the burners wherever matches or the like; Furthermore there is no necessity for heating tubes and the I ger roIn explosionand fire is reduced to a minimum. Neither is it necessary to stoop or bend over to light burners arrangedin low positions, and the lighting may be done from a distance if desired. The arrangement shown in Fig. l is diagrammatic and burners may be arranged in any desired position.

The burners 2-3 and-3 are ofordinary type, and the spark plugs are arranged with their terminals in position to have the spark in the line of the-discharge from the burners.

It will be evident that whenever the switch arm'is in contact with anybutton lo or 16,

the plug may be caused to spark by depressing the push button 26, and so long as this button is not depressed, no spark will be generated. Hence it will be readil understood that the current cannot be left turned on through negligence thereby exhausting the battery. Whenever --the hand is removed from the push button the circuit is broken, regardless of the position of the switch arm. The switch arm is the selector element of the switch, and the push button isthe timer element. It will be evident that a series of sparks might be created at named contact member,

arranged may be ignited without the necessity of using either burner by depressing the push button successively.

I claim l l. A device of the character specified, for selecting and distributing electric current to a series of spark plugs, and comprising a plate having a series of contact plates or buttons at one end, and adapted for connection with the several plugs, a switch arm pivoted to the plate and adapted to contact with the respective buttons, and adapted for connection with one of the electrical circuit, a contact member for connection with the other terminal, a resilient contact arm connected with the switch arm and normally out of contact with the lastand having a push button for permitting thesaid arm to be moved into contact with the said contact pivoted to the-plate and adapted to contact with the respective buttons, and'adapted for connection with one of the terminals of an electrical, circuit, a contact member for connection with the other terminal, a resilient contact arm connected with the switch arm and normally out of contact with the lastnamed contact member, and adapted to be moved into contact with the said contact member to close the circuit. v

3 In combination with a series of spark plugs, a high tension jump spark coil, a source of electrical energy, and an open circuit in which the coil and the source are interposed, of a support, a series of binding 7 posts on the support, each post being concircuit.
